The eatery said anyone with the last name "Burger" or variations ranging from "Berger" to "Rosenberger" will receive a free Classic Smash at any location across the United States Tuesday with a proof of identity.
"Burgers are an iconic American food. We've been eating them for generations and burgers are America's favorite food," Smashburger founder Tom Ryan said. "But just in the last five years or so, we have seen an explosion in people's interest to eat higher quality burgers than the typical fast food fare. And with the average person eating 43 hamburgers per year, there is cause for celebration of a national holiday or 'National Burger Day.'"
